Fennec® has its own personality. A very performance-oriented one. Every breath, every movement and most certainly every bit of physical exertion costs energy. The largest part of it is used by the athlete to cool his body. According to scientific studies, even up to 97 %. That's why X-BIONIC® has put everything it has into supporting the natural cooling process and into saving energy. With the Fennec® line the developers have succeeded at a break-through. While the innovative material xitanit™ reflects heat, the 3-dimensional structure increases the evaporative process of sweat directly on the skin. The body stays cool, the athlete holds onto his performance temperature longer.
